ABSTRACT:
An error detection method is provided for receiving input data which are attached with error detection codes and then subjected to a convolutional coding operation, subjecting the input data to an error correction Viterbi decoding operation, calculating and storing branch or path metrics and, at the time of detecting an error in the error detection codes, independently detecting either one of a plurality of error detection blocks having the error present therein.
